Abstract

Mlultiatom interactions required in the statistical models used for the study of both the stability of ordered structures in the ground state and the chemical short range order, have been computed from the electronic structure for transition metal alloys. It is shown that : i) the most important interactions coming from “d” bands are those corresponding to self-retraced paths, the contributions of compact clusters being negligible ; ii) in general the results obtained using only second order pair interactions are valid provided that the concentration dependence of the pair interactions is taken into account. However in a few peculiar cases these results may be qualitatively modified.
